Step-by-step explanation:
By Exterior Angle theorem,
80° + (6y + 3)° = (155 - 2y)°.
=> 6y + 83 = 155 - 2y
=> 8y = 72
=> y = 9.
Answer:
The formula to determine the population of penguins at the end of the 7th year is:

Step-by-step explanation:
With this information, we know that the initial population at end of year 0 is 1000 penguins.
The first year will born 500 chicks (50% of the population) and also 20% of the total population will die.
We can then model the population for the end of year 1 as:

As this dynamic will continue with the years, we can generalize as:

Then, the value of the population at the end of the 7th year should be:

Answer with Step-by-step explanation:
We are given that

We have to find T,N and B at the given point t > (1,
,1)



Now, substitute t=1













The answer to this is letter D
